"Excellent" Swindle said, proceeding to slam a Dark Energon charge on the Kryptonian. Hopefully that'd hold her down for a bit. The rest of the combaticons transformed. If they didn't have weapons on their person, their vehicle forms would. They charged into battle, the Autobots only now realizing that they were under attack. By then it was too late, the nearest bots were piles of scrap. The two that Kara had helped earlier, were the first to die. In total, the first charge claimed the lives of 5 Autobot soldiers.
The autobots that Kara had saved didn't even know what had hit them. They simply exploded in the wake of the rockets and gunfire from the Combaticons. The three soldiers near them suffered the same fate. By then, the Autobot's had begun to take cover, one cove nearer the 'Cons was soon overtaken.
Vortex, Swindle, and Brawl took out this small group. Swindle grabbed his target by the back, pulling him down and smashing his head. The one Vortex was after had a energon sword through the back of his neck and out his throat, and fell, leaking energon to the floor. The last one possibly had the worst death. He had turned around in enough time to see the con about to kill him. He had his optics ripped out, then his spark torn out through his chest.
By then, the Autobot's began responding. Prime being one of the first. However, Swindle had just the thing for him. An EMP grenade to the face should slow the bot down a bit. The Titan-class Autobot's were a different story. As their X-18's opened up, the Cons had to take cover. "We did great, but now's the time to retreat" Onslaught ordered. After a few seconds, the cons started to retreat. leaving behind them a trail of carnage and death.
